A Joana gostava de saber qual a intensidade de corrente que percorre o seu secador de cabelo e o valor da sua resistĂȘncia elĂ©trica. Para isso, utilizou o manual de instruçÔes para saber a potĂȘncia do aparelho e verificou que esse valor era de 2000W. A corrente elĂ©trica que utiliza na sua casa tem uma diferença de potencial de 220 V. Podes ajudĂĄ-la ?
